Can Vantara solve Colombia’s hippo problem?, Pg12

Key Highlights:

• Vantara, a wildlife rescue center in Gujarat, has offered to take in 80 hippos from Colombia that were scheduled for euthanasia.
• The hippos are descendants of four hippos imported by drug lord Pablo Escobar in 1981.
• Colombia declared Hippopotamus amphibius an invasive alien species in March 2022.
• A sterilization program began in October 2021 but was deemed ineffective.
• Peer-reviewed studies suggest that the hippos have altered ecosystem metabolism and increased nutrient loading in Colombian lakes.
• CITES inspected Vantara following allegations of discrepancies in animal imports and initially recommended halting further import permits.

Detailed Insights:

• The Colombian government decided to cull the hippos due to their rapid population growth and the high costs associated with managing them.
• Moving hippos is difficult due to their thick skin, aquatic habitat, and the risk of capture myopathy, which can lead to death during translocation.
• Housing 80 hippos at Vantara would require multiple separate pool complexes to accommodate their natural pod behavior and the climate difference.
• The CITES Secretariat team's inspection of Vantara was prompted by allegations of discrepancies in animal imports from Congo, Mexico, and elsewhere.
• Despite Vantara's offer, experts suggest that no single intervention is sufficient to manage the hippo population, and a combination of methods is needed.
• Studies show that lakes containing hippos in Colombia showed altered ecosystem metabolism, elevated nutrient loading and phytoplankton communities increasingly dominated by cyanobacteria.

Key Concepts Involved:

• Invasive Alien Species: A species introduced outside its normal distribution, threatening native ecosystems.
• Capture Myopathy: A condition in wild animals resulting from stress during capture, leading to muscle damage and potential death.
• Ecosystem Metabolism: The sum of all biological processes that occur in a particular ecosystem.
